According to http://www1.folha.uol.com.br/mercado/2017/12/1944853-energia-eolica-e-solar-atingem-patamar-mais-baixo-de-precos-no-brasil.shtml http://www1.folha.uol.com.br/mercado/2017/12/1944853-energia... in the auctions at the end of 2017 (for new generators to be built) it was around R$ 145/MWh for solar and R$ 98/MWh for wind. I don't know where to find the cost for all currently operating generators.
